Subject: [PATCH] convert_linux: remove LVM2 "devices file"
|
|
|
|
A recent feature of LVM2 is the "devices file"
|
|
<https://man7.org/linux/man-pages/man8/lvmdevices.8.html>. It speeds up
|
|
LVM2 PV discovery on a normal system, but an old devices file in a
|
|
converted domain (with different hardware) can prevent the assembly of
|
|
volume groups.
|
|
|
|
In particular, when converting a physical system to a guest with virt-p2v,
|
|
the original system will have used "sys_wwid"-type identifiers in the LVM2
|
|
devices file, and those are guaranteed not to match any virtio-blk disks
|
|
in the output domain.
|
|
|
|
We've seen a similar issue in the past under RHBZ#1164853, so just extend
|
|
the same scrubbing with the new pathname.
